acteristics
The average increase of capacitance over the
working range is 55pF. For the range of
0–98% RH linear approximation is possible, errors
will be lower than < ± 2% RH.
The sensor characteristic is determined by the
following linear formula:
C(RH) = C0 * [1+HC0 * RH]
with HC0 = 3420 ± 250 ppm /% RH
relative humidity [% RH]
temperature [°C]
For high accuracy requirements, the sensitivity is determined by the following polynomial:
C(RH) = C0 * [1 + HC0 * RH + K(RH)]
whereby:
K(RH) = A1*RH+A2*RH1.5+A3*RH2+A4*RH2.5
A1 = 2.6657E-3
A2 = -9.6134E-4
A3 = 1.1272E-4
A4 = -4.3E-6
